compare two columns and their corresponding values from two different excel files

Hi,

I’m trying to compare two columns and their corresponding values from two different excel files. I want to know what values from column one in spreadsheet one matches column one in spreadsheet two but their corresponding values are not the same. And I want to print those different values.

Below I have a list of countries and their corresponding cities, I mismatched some of them for example ALGERIA and it’s corresponding is ALGIERS but in the second document it has TIRANA as corresponding city. I want to show that difference. I used ismember function but I don’t think this is an accurate approach.

Data = readtable("Data.xlsx")
Data2 = readtable("Data2.xlsx")
Matches = ismember(Data.country,Data2.country) & ~ismember(Data.city,Data2.city)

I would think if you read the data in as string matrices, ismember can be used to compare rows. This would allow you to find all matching rows, and assume that non-matching rows are wrong.

I tried that and readmarix doesn't really work with this particular case!

>> data1=readtable('data.xlsx');data2=readtable('Data2.xlsx');
>> setdiff(data1,data2,'rows')
ans =
  3×2 table
       country           city    
    _____________    ____________
    {'ALGERIA'  }    {'TIRANA'  }
    {'ARGENTINA'}    {'CANBERRA'}
    {'AUSTRALIA'}    {'ALGIERS' }
